The same thing is true on "My Lesbian Maid" and an upcoming release from AVN called "No Limits". I think the relationship between AVN and Scala is getting closer and closer. (Scala started to produce AVN's DVDs a little while ago.) That's the only thing I can think of to account for it. They're still listed as a separate label on Scala's B2B website; actually they draw a distinction between AVN in general and the Sinners line in particular.
